Hello,
I dont recommend it but, I have done it.
I have used Small Rifle in place of Small Pistol primes in the past and looks like I will need to do so soon. Do your homework, start low with a hard to ignite powder that can be loaded light, ball powder is best because its harder to ignite then flake powder. I have only done this with Accurate #2 for 9MM loads, 4gn under a 124gn projectile worked great.
